Daniel Kahneman, recipient of the Nobel Prize in Economic Sciences for his seminal work in psychology challenging the rational model of judgement and decision-making, is one of the world's most important thinkers. His ideas have had a profound impact on many fields – including business, medicine and politics – but until now he has not brought together his many years of research in one book. In Thinking, Fast and Slow, Kahneman takes us on a groundbreaking tour of the mind and explains the two systems that drive the way we think and make choices. One system is fast, intuitive, and emotional; the other is slower, more deliberative, and more logical. Kahneman exposes the extraordinary capabilities - and also the faults and biases - of fast thinking, and reveals the pervasive influence of intuitive impressions on our thoughts and behaviour. The importance of properly framing risks, the effects of cognitive biases on how we view others, the dangers of prediction, the right ways to develop skills, the pros and cons of fear and optimism, the difference between our experience and memory of events, the real components of happiness – each of these can be understood only by knowing how the two systems work together to shape our judgments and decisions. Drawing on a lifetime's experimental experience, Kahneman reveals where we can and cannot trust our intuitions and how we can tap into the benefits of slow thinking. He offers practical and enlightening insights into how choices are made in both our professional and our personal lives – and how we can use different techniques to guard against the mental glitches that often get us into trouble. Thinking, Fast and Slow will transform the way you take decisions and experience the world. 'There have been many good books on human rationality and irrationality, but only one masterpiece. That masterpiece is Daniel Kahneman's Thinking, Fast and Slow.' Financial Times 'Thinking, Fast and Slow is a masterpiece - a brilliant and engaging intellectual saga by one of the greatest psychologists and deepest thinkers of our time. Kahneman should be parking a Pulitzer next to his Nobel Prize.' Daniel Gilbert, author of Stumbling on Happiness 'Daniel Kahneman is one of the most original and interesting thinkers of our time. There may be no other person on the planet who better understands how and why we make the choices we make. In this absolutely amazing book, he shares a lifetime's worth of wisdom presented in a manner that is simple and engaging, but nonetheless stunningly profound. This book is a must read for anyone with a curious mind.' Steven D. Levitt, co-author of Freakonomics 'Daniel Kahneman is among the most influential psychologists in history and certainly the most important psychologist alive today. He has a gift for uncovering remarkable features of the human mind, many of which have become textbook classics and part of the conventional wisdom. His work has reshaped social psychology, cognitive science, the study of reason and of happiness, and behavioral economics, a field that he and his collaborator Amos Tversky invented. The appearance of Thinking, Fast and Slow is a major event.' Steven Pinker, author of The Better Angels of our Nature 'This is a landmark book in social thought, in the same league as The Wealth of Nations by Adam Smith and The Interpretation of Dreams by Sigmund Freud.' Nassim Nicholas Taleb, author of The Black Swan 'This book is a tour de force by an intellectual giant; it is readable, wise, and deep. Buy it fast. Read it slowly and repeatedly. It will change the way you think, on the job, about the world, and in your own life.' Richard Thaler, co-author of Nudge
